How real do the breasts feel on a RealDoll?

We use a special formulation of silicone which has a gelatinous consistency. This special silicone gel is used inside the RealDoll breasts to make them look, feel, and bounce like real breasts. The silicone gel is cured silicone rubber and is completely dry; it is not a liquid so a RealDoll’s breasts cannot leak. Typically the breasts will be a little firm when your doll arrives but they will soften with time.
